Abstract
A cooling microcircuit for use in a turbine engine component, such as a turbine blade, having an airfoil portion is provided. The cooling microcircuit has at least one inlet slot for introducing a flow of coolant into the cooling microcircuit, a plurality of fluid exit slots for distributing a film of the coolant over the airfoil portion, and structures for substantially preventing one jet of the coolant exiting through one of the fluid exit slots from overpowering a second jet of the coolant exiting through the one fluid exit slot.
